Studies of transfermium nuclei, which are amenable to detailed spectroscopy, help to constrain models which predict the structure of superheavy nuclei. We have performed a decay spectroscopy experiment focused on the odd-Z nucleus ²⁵¹Md, populated via the ²⁰⁵Tl(⁴⁸Ca,2n) reaction at the ATLAS facility of Argonne National Laboratory.  Fusion-evaporation residues were separated from the beam and identified at the focal plane of the Argonne Gas Filled Analyzer (AGFA).  The X-Array was placed surrounding the AGFA focal plane such that γ rays emitted from a high-K isomer could be observed populating rotational bands.  The results of the experiment will be presented and the nuclear structure implications will be discussed.
